Hi all,
After merging the net-next tree, today's linux-next build (x86_64
allmodconfig) failed like this:
net/ipv4/fou.c: In function 'gue_gro_receive':

Caused by commit
d4546c2509b1 ("net: Convert GRO SKB handling to list_head.")
from the net-next tree interacting with commit
603d4cf8fe09 ("net: fix use-after-free in GRO with ESP")
from Linus' tree.
I took a guess and aplied the following merge fix patch:
